# AT90S2313 Demo board

It is a `KiCAD` files for the demo board I made to play with `at90s2313` microcontrollers.

## Features

  * SPI port for device programming
  * PINB header
  * PIND header
  * Separate GND TXD RXD header which is extremely useful in such sequence.
  * Header for Oscillator
  * Two buttons which is connected with INT0 and INT1 correspondingly
  * Two LEDs

I don't mess with those "fancy" labels which could be placed to the pcb
by manufactures because I prefer the DIY way:

## Usage

The controller itself works just fine with almost any crystal, it is fun to play
with those XTAL pins :)

To make it work I use 16Mhz crystal and USBAsp programmer.
